11 (0x0B) Get Comm Event Counter
Every time a request is processed by the slave device, 1 is added to the event counter.
The counter does not increase when there is a frame error or when other counters are being read.
The master device reads this counter before and after a request to judge whether it has been
processed or not.
The status is generally 0x0000 when the slave device is not busy.
e.g.) Event counters are read.
The example shows that the slave device is not busy (0x0000) and that it has processed a total of
264 (0x0108) commands.
